Alkotest wall-mounted elbow KWW2012 KOLANKO GW FI20X1/2 for plumbing connections

Alkotest wall-mounted elbow KWW2012 (KOLANKO GW FI20X1/2) is a compact plumbing fitting designed to create a secure 90° connection between a 20 mm supply pipe and a 1/2" female threaded outlet. Intended for fixed wall installations in residential and commercial water systems, this elbow provides a stable transition from in-wall piping to fixtures or flexible hoses. The design supports common potable water and utility connections where a professional, space-saving right-angle outlet is required.

Advantages

The wall-mounted elbow offers a robust and compact solution for turning a 20 mm pipe into a standard 1/2" threaded outlet with minimal protrusion from the wall. Its fixed-wall design ensures stable support for attached fixtures and reduces stress on pipe joints. The fitting is suitable for installations where a clean, fixed outlet point is needed and simplifies connection to taps, hoses, and other threaded plumbing components.

Suitable for

• Connecting in-wall 20 mm water supply lines to 1/2" threaded fixtures
• Fixed wall outlets for faucets, washing machines, and dishwashers (where compatible)
• Residential and commercial potable water installations requiring a compact elbow

Key specifications

• Pipe connection diameter: 20 mm
• Outlet thread: 1/2" female (internal) thread
• Angle: 90° elbow
• Mounting type: wall-mounted / fixed-wall connection
• Intended media: potable water and general water supply

How to use

Mount the elbow into the prepared wall opening and connect the 20 mm pipe using the appropriate joining method for the system (e.g., compression, push-fit, or soldering where applicable and compatible). Secure the fitting so the 1/2" female thread is correctly oriented for the intended fixture. Apply thread sealant or tape to the male threaded fitting before connecting the fixture or hose, and test the connection at working pressure to verify there are no leaks. Follow local plumbing codes and installation practices when integrating the elbow into your system.

Usage recommendations

Use the elbow with compatible 20 mm piping materials and ensure the 1/2" male thread on the fixture matches standard plumbing dimensions. When installing in potable water systems, use approved sealing materials and check for compatibility with the pipe joining method to maintain system integrity and prevent leaks.
